Another way to (slightly to greatly depending on your network) increase performance on networks that take very long for DNS resolutions is to use BIND server installed in a caching only configuration, with the OpenDNS server (or another DNS server) set as forwarders.
For instructions on how to accomplish this, have a look at https://help.ubuntu.com/community/BIND9ServerHowto#Caching%20Server After you set this up, you need to modify /etc/dhchp3/dhclient.conf and modify this line prepend domain-name-servers 127.0.0.1 (uncomment it if it is already commented). This is to ensure that NetworkManager always assigns your local system as the most preferred DNS server. I have achieved great speedups in DNS lookups (you can test this using dig). Try it at your own risk, though.
